Topological lattice using multi-frequency radiation
We describe a novel technique for creating an artificial magnetic field for ultracold atoms using a periodically pulsed pair of counter propagating Raman lasers that drive transitions between a pair of internal atomic spin states: a multi-frequency coupling term. In …

Dr. Lauren M. Aycock defended her thesis today.
Lauren defended her thesis titled “Topological excitations in a Bose gas & sexual harassment reported by undergraduate physicists” today to a bumper audience in Ithaca. And it rocked!
Magnetic phases of spin-1 spin–orbit-coupled Bose gases
Phases of matter are characterized by order parameters describing the type and degree of order in a system. Here we experimentally explore the magnetic phases present in a near-zero temperature spin-1 spin–orbit-coupled atomic Bose gas and the quantum phase transitions …

Gauge matters: observing the vortex-nucleation transition in a Bose condensate
The order parameter of a quantum-coherent many-body system can include a phase degree of freedom, which, in the presence of an electromagnetic field, depends on the choice of gauge. Because of the relationship between the phase gradient and the velocity, …
